Carried in guides secured 100 spider 4. Formed on the base 1 is a central to two of the uprights 42 is a sliding bar 38 hub 5 in the bore of which -is an externally having an arm 39'. A pin in this arm extends threaded sleeve 6 which may be adjusted verthrough a slot 40 in an arm 41 secured to the tically by means of a nut 7 having formed collar 28 so that movement of the1 collar 5J in its periphery a number of recesses 8 adaptaround the shaft will cause the bar 88 to slide 105 ed to receive one end of a lock bar 9.

the loch bar 9. This construction enables me Surrounding and keyed to the sleeve 27 is 110 ranged adjacent to the cap openingsare cap guides 48 having their outer edges spaced`.

- from the cap disk to accommodate a cap supporting plate hereinafter to, be described. Mounted on the disk 44 directly above the cap openings 47 are plunger guides 49 1n each of which is a reciprocating plunger 50. Adjacent to its' top end each plunger is pro- 'vided with a disk 51 having conical upper and lower faces. Against the lower face of each of these disks bears a tapered coil sprinl 52 tending to raise the plunger. Surroun ing the 'sleeve 43 is a sleeve 53 carrying a track 54. The sleeve 53 is capable of a slight longitudinal adjustment by means of nuts 55 engaging with threaded portions on the sleeve 43 so that the track may be positioned ,accurately with relation to the plungers. Carried on the track is a cam block .formed of two parts 56 and 57 adapted to be adjusted along the track by means of clamps 58. The part 57 is provided with a tongue 59 overlapping the part 56 so that the effec- Extending parallel with the face 61l is a lift` 'tive length of the block may be varied. Adjacent to the end of the part 56 is a projection terminating in an inclined face'61.

ing cam 62 secured, to the track by clamps 63.

' AThis lifting cam is adapted to engage with the disks 51 and thus positively lift tiicplungers to their normal positionas the springs 52 might fail todo this in the event of unusual .friction on the plungers.

Caps are delivered to the cap disk 46 by a conveyor 64 (Figure 18) the end of which is carried on a bracket 65 (Fig. 9) forming l part of al cross bar 66. On each end ofthe cross bar 66 are twogrooved wheels 67 movingr on one of the uprights 2 as a guide. Connecting the cross bar 66 witha second cross bar 68 are a pair of straps 69, the bar 68 being also provided with guide wheels 67.

The two bars and two straps thus constitute a vertically movable carriage for supporting and positioning the inner end of the cap conveyor. In order that the carriage may be raised and lowered automatically with the cap disk when the latter is adjusted for cans of different heights, I support .the cai'- riage from the plunger disk 44 by means ot a pair. of wheels 70 on the straps 69. 4 Carried on the center rail `of the cap conveyor is a finger 71 Which is adjustable by means of a screw 72 passing through a slot 73. Secured to the left hand side of the conveyor, adjacent to the finger 71 isja block 74. Pivoted to the block 74 at 75 is a second block 76 normally held against a stop 77 by a spring 78 secured at one end to a pin in the block 76 and at'the other to an arm 79 on one of the straps 69. Pivotedat 80 to the block 70 is a tinger 81 to which is secured a spring 82 forcing ,the caps into the recesses of the cap guides 48 to position them over the openings 47'. Movement of the finger 81 on. the pivot 80 is limited positivelyin one direction by a pin 83 and adjustably in the otherby a screw 84 threaded in the block 76 and provided with a lock nut 85. A projection 86 on the block 76 extends adjacent to the spring 82 lo prevent the latter from being bent so far as to permanently change its shape. Arranged betweenthe capconveyor and its supporting bracket is a landing plate 87 extended at one side to provide a pivot 88 for an auxiliary yielding landing plate 89 which projects over the opening 47, 'as shown in Figure 18, so as rod 92 at each side of the tail piece und provide means for`varying the tension of the spring. The screw s top enables the normal position of the plate 89 to be varied for different sizes of caps and 'a lock nut 95 serves to secure it in position.

'The plunger disk 44 is provided on its periphery with'teeth 100 meshing with a pinion 101 on a shaft 102. This shaft is journaled at its lower end in a box 103 carried on across bar 104 clamped to the" uprights 2 and carrying brackets 105 for the can conveyor. As the conveyors are the same as those shown in my filling machine, above referred to` they have not been shown here. They are actuated from a shaft 106 driven by a sprocket chain 107 passingr around a sprocket wheel 108 on said shaft and a sprocket wheel 109 on a shaft 110 journaled in boxes 111 clamped to the uprights 2. 'This shaft passes through vbearings 112 of a ,yoke 11S-also provided gear wheel l15 1neshing with a bevel geur.

lwheel 1116 on the shaft 110. Moui'ited ou one end of the shaft 110 is a combined clutch and driving pulley 117 by means of which power is applied to the machine. The haudle 118 ofthe clutch travels in a guide bracket 119 secured to one of the uprights and terminating in a shoe 120 against which hears the end of the sliding bar 38. A hand wheel 1 21 provides means for manually operating the machine.

Mounted on the shaft 110 is a sprocket wheel 122iaround which passes a sprocket chain 123 also passing around a sprocket wheel 124 on afstud 125 carried on the upright 2. The sprocket wheel 124 is secured to a pulley 126 connectedl by a bolt 127 to a pulley operated by a rod 132'extending to the front tlf) of the machine and provided with a hand knob 133. A bracket 134 secured tothe cam track 54 engages one of the uprights 2 to prefvent rotation of the'track.- Pivoted to this bracket is a lever 135 provided with a cam tace 136 in the path of the plungers 50.- Extending from this lever to the cap feeding de,- vice (not shown) is a feed control rod 139.

a set screw 137 and the sleeve43 is .raised or lowered by means of a hand wheel 138,

as in my prior application above referred to.

rll`he other parts not described in detail will be understood tol besimilarto 'those shown and described in said application. 'A

r1`he operation of my machinebrieiy described is-as iol/lows: Cans are fed onto the can table 2b and into the recesses of the guides or holders 37 by the can conveyor l(not shown) 'carried by the left hand bracket 105 (Figures 2 and'9). This can table is rotated in a clockwise direction to bring the cans in line with the cap conveyor 64'wher'e a cap is fed intolthe caipdisk 46 and into the recess ot the holder 48 so as to be positioned directly over the can. Plate 89 supports the cap at this point and-so prevents it Jfrom irrimediately dropping into 4the opening 47. As the cap is carried forward the spring 8 2 insures its proper seating in the recess ot thcdiolder. Atthe same time the can is raiser. into the cap disk 416 by hthe action of the track 23 on the plunger 24 of the can support 25 carrying the can and the corresponding capplunger 50 is lowered by the action of the cam block 57. K The cap is thus orcedon the can and the'parts remain in this relation as they travel forward until the'cap plunger cornes'in contact -with the projection of the cam block 56 and'is forced downwardly. At the same time the can plunger 24 is lowered by reach-l ing the end of the raised part ot' the track 23 and thus the capped can is forced out of the cap disk and returned to normal position. Spring 52 now raises the cap plunger as it 4contacts with the 4inclined face 61. Should the spring for any reason prove insuiiicient for the purposeV the lifting cam 62 will insure this action. The capped can is now"car ried forward and discharged in the conveyor (not shown) on the right hand bracket 105. lln case the can plunger fails to return to normal position or any other obstruction .occurs on the can table such obstruction will strike the lip 36on lever 31 causing collar 28 to rotate. This movement is vcommunicatedy vthrough slotted arm 41 and arm 39 to uthe Sliding bar 38 and the'nce to the clutch lever 'on account of the momentum of the moving parts so when the bar 38 has reached the end Aof its movement pressure on the lip 36 overcomes the tension of the spring 33 and the lever 31 turns on its pivot allowing the obstruction to pass withoutinjury to the mechanism.
